In order to optimize the exhibition layout of the memorial hall and enhance the user’s experience of the exhibition system of the exhibition hall space of the memorial hall, an integrated exhibition system of the exhibition hall space of the memorial hall based on virtual reality is designed. The data organization layer of the memorial hall collects the image data of the exhibition hall and exhibits of the memorial hall by using equipment such as a camera, a sensor and the like, analyzes the collected two-dimensional image data into a DICOM3.0 standard data format through an image analysis module, and preprocesses the image by using an image enhancement method based on visual perception so as to obtain scene data of the memorial hall; Based on the scene data, 3D MAX software is used to construct the 3D model of the exhibition hall and exhibits of the memorial hall according to the spatial layout and shape characteristics of the exhibition hall, and the rendering and baking of the model are implemented; The virtual display layer of the memorial hall is based on the three-dimensional model of the exhibition hall and exhibits, and realizes the visual virtual display of the memorial hall by means of three-dimensional display and panoramic roaming. The experimental results show that the system model has high precision and can provide users with a better sense of interaction and immersive experience.
